Alstroemeria plant named ‘Zalsabrand’

ABSTRACT

A new and distinct cultivar of  Alstroemeria  plant named ‘Zalsabrand’, characterized by its erect and strong flowering stems; vigorous growth habit; intense light purple-colored flowers; and good postproduction longevity.

Botanical designation: Alstroemeria hybrida.

Cultivar denomination: ‘Zalsabrand’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrida, commercially used as a cut flower Alstroemeria, and hereinafter referred to by the name ‘Zalsabrand’.

The new Alstroemeria is a product of a planned breeding program conducted by the Inventor in Hillegom, The Netherlands. The objective of the breeding program was a develop new cut flower Alstroemeria cultivars with desirable flower and plant qualities, attractive flower colors and excellent postproduction longevity.

The new Alstroemeria originated from a cross-pollination made by the Inventor in June, 1997 in Hillegom, The Netherlands of a proprietary Alstroemeria hybrida selection identified as 97-473-4, not patented, as the female, or seed, parent with a proprietary Alstroemeria hybrida selection identified as 94-531-1, not patented, as the male, or pollen, parent. The new Alstroemeria was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Hillegom, The Netherlands in April, 1998.

Asexual reproduction of the new cultivar by root divisions in a controlled environment in Hillegom, The Netherlands, since August, 1998, has shown that the unique features of this new Alstroemeria are stable and reproduced true to type in successive generations of asexual propagation.

SUMMARY OF THE INVENTION

Plants of the cultivar Zalsabrand have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Zalsabrand’. These characteristics in combination distinguish ‘Zalsabrand’ as a new and distinct cultivar:

-   -   1. Erect and strong flowering stems.     -   2. Vigorous growth habit.     -   3. Intense light purple-colored flowers.     -   4. Good postproduction longevity.

Plants of the new Alstroemeria can be compared to plants of the female parent selection. In side-by-side comparisons conducted in Hillegom, The Netherlands, plants of the new Alstroemeria differed from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Alstroemeria had larger flowers than plants         of the female parent selection.     -   2. Plants of the new Alstroemeria had darker purple-colored         flowers than plants of the female parent selection.

Plants of the new Alstroemeria can be compared to plants of the male parent selection. In side-by-side comparisons conducted in Hillegom, The Netherlands, plants of the new Alstroemeria differed from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Alstroemeria had larger flowers than plants         of the male parent selection.     -   2. Plants of the new Alstroemeria had darker purple-colored         flowers than plants of the male parent selection.

Plants of the new Alstroemeria can also be compared to plants of the cultivar Flamengo, disclosed in U.S. Plant Pat. No. 6,382. In side-by-side comparisons conducted in Hillegom, The Netherlands, plants of the new Alstroemeria differed from plants of the cultivar Flamengo in the following characteristics:

-   -   1. Plants of the new Alstroemeria had longer flowering stems         than plants of the cultivar Flamengo.     -   2. Plants of the new Alstroemeria and the cultivar Flamengo         differed in flower color as plants of the cultivar Flamengo had         red and white-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Alstroemeria, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Alstroemeria. The photograph comprises a side perspective view of a typical flowering stem of ‘Zalsabrand’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants of the new Alstroemeria grown in Rijsenhout, The Netherlands in a glass-covered greenhouse in ground beds. During the production of the plants, day temperatures ranged from 15° C. to 20° C. night temperatures ranged from 10° C. to 15° C., soil temperature was about 14° C. and light levels averaged 5,000 lux. Plants used for the photograph and description were about one year-old. The photograph and the description were taken during March and April, 2005. Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
